Yes, I think that if you put a lot of work into it you might be able to down trollgore as a 5x shaman team and then run past the next two bosses and down the final boss. You'll get some epic leather spellcaster legs and bracers for elemental shamans. If you can get it as a heroic daily, maybe you could get 4 badges out of it. It's not much, but with the current gear it might be the best you can get. Still, downing trollgore might take full buffs to pull off because he can still hit relatively hard.
